A water-soluble tetrazolium reagent that serves as a sensitive chromogenic indicator for NADH. It is reduced by NADH at neutral pHs in the presence of 1-methoxy PMS to produce the corresponding formazan dye that absorbs at 438 nM. Useful in cell proliferation assays as a cell viability indicator.
Synonyms: 2-(4-Iodophenyl)-3-(4-nitrophenyl)-5-(2,4-disulfophenyl)-2H-tetrazolium, monosodium salt
